Searching the internet (in sites like SPCR) i’he found the components that match my desidered build:

– Case: Hd-Plex 5 second generation fanless case.
This case is stated to support up to 95 TDW CPU whit eight copper heat pipe cooling.
It is not the smallest case but can accept atx motherboard and has a lot of space to support
upgrades / new internal component.
It can accept a low power discrete card that can be passively cooled with
additional pipes.

– CPU: Intel I5 5675C.
It suits my needs because is a desktop class (not underpowered laptop) 65W TDP I5 and it
has an integrate Iris Pro 6200 gpu adeguate for my usage (at this time i don’t want a discre
gpu).

– HD: Samsung SSD EVO 850 500GB in M.2 format (sata,ahci)
I like the compact form M.2. The sata,ahci version is the “slower” type of M.2 but costs
less for GB then pcie,nvmi and is more than adequate for general purpose usage.

-MB: Asus Z97-P.
It as a Z97 chipset, M.2 socket and support 4K HDMI.

– OTHER : no need for other internal component (DVD , Hard Disk) because if needed i use
external usb version.

So i built the PC.

Below some pictures of the internals and external of the finished PC.

My impression of the main fanless components from HD-PLEX (case, cpu cooling and PSU) is good, they seems quality built.
